Mean Reversion vs Trend Following

Every trading strategy falls into one of two camps: mean reversion or trend following. The philosophy behind each, and when each works best, determines which strategy you deploy in any given market.

The Two Approaches

strategies buy oversold conditions expecting a bounce back to average. Examples: RSI-2, RSI-25 ETF, Bollinger Band bounces.

strategies buy momentum expecting continuation. Examples: Holy Grail, 50-50, breakout systems, moving average crossovers.

When Each Approach Works

Neither approach works all the time. Market conditions cycle between trending and ranging, and the wrong strategy for the current regime loses money.

The Market Condition Question

Before choosing a strategy, always ask: "What is the current market regime?" Check if the S&P 500 is above or below its 200-day SMA (trend direction) and whether the VIX is above or below 20 (volatility regime). This two-axis framework gives you four regimes: trending-calm, trending-volatile, ranging-calm, ranging-volatile.

The Multi-Strategy Approach

Professional traders maintain a toolkit of strategies and deploy the one matching current conditions.

Starting out: Master one strategy completely before adding another. Your personality determines the best first choice:

Common Mistakes

Strategy Discipline

If you enter a mean-reversion trade, follow mean-reversion exit rules (time stops, indicator exits). If you enter a trend trade, follow trend exit rules (trailing stops, MA crosses). Mixing entry rules from one approach with exit rules from another produces incoherent results.

Level 6 Roadmap

Mean Reversion: RSI-2 (Connors), RSI-25 for ETFs (Connors)

Trend Following: Holy Grail (Raschke), 50-50 (Schaap), Breakout Strategies, Pullback Strategies

Specialized: Gap Trading, Sector Rotation, Options Basics, Strategy Selection Framework

Each lesson provides complete rules (entry, exit, stops) so you can backtest and implement them.

Key Takeaways

Every strategy is either mean reversion (buying weakness) or trend following (buying strength)
Mean reversion works best in range-bound markets; trend following in trending markets
Neither works all the time, so market regime identification is critical
Master one approach first, then add the opposite to cover more conditions
Never mix entry rules from one approach with exit rules from the other

20 XP

Pull up a daily chart of the S&P 500. Identify the current regime: is the market above or below the 200-day SMA? Is the ADX above or below 25? Based on these two data points, which approach, mean reversion or trend following, would you favor right now?
